Pulmonary Valve Implantation

Ten cases of elective late pulmonary valve implantation after repair of tetralogy of Fallot were reviewed. The interval after initial repair ranged from 1.5 to 43 years (mean, 20.0 ± 12.3 years). There was no hospital mortality or late death during a mean follow-up of 12.5 months. Preoperatively, 9 patients were in New York Heart Association functional class III–IV; after pulmonary valve implantation, all 10 patients were in class I–II (average improvement, 1.7 classes). Left ventricular ejection fraction improved significantly (from 62.1% ± 4.7% to 70.2% ± 4.9%), as did fractional shortening (from 34.0% ± 5.0% to 40.0% ± 4.2%). Right ventricular diameter decreased significantly (from 32.3 ± 7.5 to 24.4 ± 5.4 mm). QRS duration decreased significantly (155.2 ± 27.1 vs. 140.0 ± 21.2 msec), but there was no significant difference in QT interval (460.9 ± 29.6 vs. 451.9 ± 50.6 msec). Hospital stay was 4–7 days. One patient had preoperative ventricular fibrillation requiring resuscitation and an implantable cardiac defibrillator; another needed a defibrillator at the time of pulmonary valve implantation, because of ventricular arrhythmias. It was concluded that late pulmonary valve implantation after tetralogy of Fallot repair had significant benefits and carried low operative risk.

Background: Acute rheumatic fever (ARF) and acute rheumatic carditis (ARC) continue to be a major public health problem in developing countries. Objective: To study the characteristics of children with ARC being treated at a tertiary centre. Methods and Results: We studied 126 children (mean age 10.4 ± 2.3 years, range 5–15 years, 60% males) diagnosed with ARC by treating cardiologists. Most had lower socio-economic status. Fifty of 126 (40%) presented with a first episode of ARC. Joint symptoms were present in 29% and fever in 25%. Only 2.4% had subcutaneous nodules and none had erythema marginatum or chorea. Fifty-one percent presented in NYHA class II and 29% in NYHA class III or IV. Tachycardia and heart failure were present in 53% and 21%, respectively. Recent worsening of NYHA class (dyspnoea) was the commonest feature (48%). Laboratory investigations showed raised antistreptolysin O titres (>333 units) in only 36.7% of patients. Raised C-reactive protein (CRP) was present in 70%, while raised erythrocyte sedimentation rate was found in only 37% of patients. On the basis of above findings, the modified Jones criteria (2015) for the diagnosis of ARF were satisfied only in 46% of children. Echocardiography showed mitral valve thickening in 77% and small nodules on the tip of the leaflets in 43% (27 and 8%, respectively for aortic valve). Left ventricular ejection fraction was <50% in only 3 patients. The dominant valve lesion was mitral regurgitation (MR) (present in 95% of patients; severe in 78%, moderate in 15%), while aortic regurgitation was present in 44% (severe in 14%). Conclusions: The criteria are often not satisfied by patients being treated for ARC. Recent unexplained worsening of dyspnoea, young age, significant MR, echocardiographic nodules, and elevated CRP are important indicators.

Abstract Background Mitral valve (MV) repair with annuloplasty is the standard of care in patients with primary degenerative mitral regurgitation (DMR). Newer generations of annuloplasty rings have been developed with the goals of closer reproduction of native annular geometry and easier implantation. This study investigates the short-term and 5-year clinical outcomes of MV repair with the Carpentier-Edwards (CE) Physio II annuloplasty ring. Methods This is an observational study including a total of 486 patients who underwent MV repair for DMR using the CE Physio II annuloplasty ring between 2011 and 2016. Results Mean age was 54.8 ± 12.1 years, 364 patients (74.9%) were males, and 84 patients (17.3%) presented with atrial fibrillation. Mean left ventricular ejection fraction was 62.3 ± 7.3%. Mean logistic EuroSCORE was 2.7 ± 2.4%. New York Heart Association functional class III–IV symptoms were present in 134 (27.6%) patients preoperatively. Isolated MV repair was performed via a right-sided mini-thoracotomy in 479 patients (98.6%). Concomitant procedures included ablation for atrial fibrillation in 83 patients (17.1%) and closure of atrial septum defect in 88 patients (18.1%). Median size of implanted annuloplasty rings was 34 mm (interquartile range: 34–38 mm). Mean cardiopulmonary bypass time was 116 ± 34 minutes and mean cross-clamp time was 74 ± 25 minutes. Thirty-day mortality was 0.4%. The Kaplan–Meier 4-year survival was 98.5%. Freedom from MV reoperation was 96.2 and 94.0% at 1 and 4 years. Conclusion MV repair with the CE Physio II annuloplasty ring is associated with excellent midterm clinical outcome.

Abstract OBJECTIVES Our goal was to analyse the implantation and outcome of thoracoscopic epicardial leads after a failed endovascular approach or follow-up (FU) complications after endovascular implantation. METHODS We reviewed the records of patients with failed endovascular left ventricular (LV) lead placement or complications during FU, who were subsequently referred to cardiac surgeons for treatment with thoracoscopic LV lead implantation. We analysed the reasons for endovascular failure; the indications for the surgical procedures; and the clinical, echocardiographic and device FU results. RESULTS Between 2010 and 2013, a total of 23 patients were included. Among them, 17 of the patients had no previous cardiothoracic surgery, 13 (76%) had successful video-assisted thoracoscopy (VAT) LV lead implantation, 3 (18%) had a conversion to thoracotomy and 1 (6%) failed. Of the 6 patients with prior cardiothoracic surgery, 2 (33%) had VAT only, 3 (50%) had primary thoracotomies and 1 (17%) had a conversion. Two major complications occurred. The reasons for LV endovascular lead failure were subclavian vein occlusion (n = 2), implant failure (n = 13) and complications during the FU period (n = 8). FU information was available for 20 patients: 17 (85%) had improved symptoms. The median FU period was 33 months. A total of 78% of patients were in New York Heart Association (NYHA) functional class III–IV before the operation; 30% were in NYHA functional class III–IV at the last FU examination. The left ventricular ejection fraction increased from 25% before surgery to 31% at the last FU examination. Overall, sensing and pacing threshold values remained stable over time. In 1 patient, lead revision was necessary due to an increase in the pacing threshold. CONCLUSIONS VAT implantation of LV leads had an excellent response rate with an improvement in NYHA functional class and left ventricular ejection fraction. The lead measurements were mainly stable over time.

Abstract Background Patients with ischemic (IHD) and nonischemic (NICM) dilated heart disease and reduced left ventricular ejection fraction are at increased risk of ventricular tachycardias (VTs) or sudden cardiac death. VT catheter ablation is an invasive treatment modality for antiarrhythmic drugs-resistant VT that reduces arrhythmic episodes, improves quality of life and improves survival in patients with electrical storm. Direct comparison of the outcomes from combined and non-combined endoepicardial ablations is limited by patient characteristics, follow-up durations, protocols heterogeneity and scarcity of randomized trials. We aim to investigate the long-term clinical outcomes of these 2 strategies in the IHD and NICM populations. Methods Multicentric observational registry including 316 consecutive patients who underwent combined (C-ABL) and non-combined (NC-ABL) endoepicardial ventricular tachycardia (VT) ablation for drug-resistant VT between January 2008 and July 2019. Chagas' disease patients were excluded. Primary and secondary efficacy endpoints were defined as VT-free survival and all-cause death after ablation. Safety outcomes were defined by 30-days mortality and procedure-related complications. Results Most of the patients were male (85%), with IHD (67%) and a mean age of 63±13 years. During a mean follow-up of 3±2 years, 117 (37%) patients had VT recurrence and 73 (23%) died. Multivariate survival analysis identified storm (ES) at presentation (HR=2.17; 95% CI 1.44–3.25), IHD (HR=0.53, 95% CI 0.36–0.78), left ventricular ejection fraction (LEVF) (HR=0.97, 95% CI 0.95–0.99), New York Heart Association (NYHA) functional class III or IV (HR=1.79, 95% CI 1.13–2.85) and C-ABL (HR=0.49, 95% CI 0.27–0.92) as independent predictors of VT recurrence. In 135 patients undergoing two or more ablation procedures only C-ABL (HR=0.36, 95% CI 0.17–0.80) and ES at presentation (HR=2.42, 95% CI 1.24–4.70) were independent predictors of arrhythmia recurrence. The independent predictors of all-cause mortality were ES (HR=2.17, 95% CI 1.33–3.54), LVEF (HR=0.95, 95% CI 0.92–0.98), age (HR=1.03, 95% CI 1.01–1.05), NYHA functional class III or IV (HR=2.04, 95% CI 1.12–3.73), and C-ABL (HR=0.22, 95% CI 0.05–0.91). The survival benefit was only seen in patients with a previous ablation (P for interaction=0.04) – Figure 1. Mortality at 30-days was similar between NC-ABL and C-ABL (4% vs. 2%, respectively, P=0.777), as was the complication rate (10.3% vs. 15.1% respectively, P=0.336). Conclusion A combined endo-epicardial approach appears to be associated with greater VT-free survival and overall survival in ischemic and nonischemic patients undergoing repeated VT catheter ablations. Both strategies seem equally safe. Survival analysis for C-ABL vs NC-ABL Funding Acknowledgement Type of funding source: None

Abstract Introduction Heart failure (HF) is categorized on the basis of the eft ventricular ejection fraction (LVEF). The European Society of Cardiology has proposed mid-range EF (HFmrEF) as a new category of HF that includes patients with an LVEF of 40–49%. However, the clinical characteristics, change in LVEF following treatment, and outcome of patients with HFmrEF remain clear. Methods We conducted a prospective observational study of Japanese hospitalized HF patients between 2015 and 2018 at a single-center (HIJ-HF III). HFmrEF was defined as 40–49% of LVEF on echocardiography at admission. We followed these patients and performed echocardiography to assess LVEF per year after hospital discharge. Clinical outcome was death from any cause. Methods and results We studied 138 patients with HFmrEF (median age 71 years, 69% male). They had 32% of ischemic heart disease, 9% of New York Heart Association functional class III or IV at discharge. During median follow-up of 20 [13–28] months, we assessed change in LVEF for 110 patients with HFmrEF. One year after hospital discharge, 49 patients (44%) improved LVEF (≥50%) and 21 patients (19%) reduced LVEF (<40%). HFmrEF patients who reduced LVEF (<40%) were significantly higher mortality rate than those who improved LVEF (≥50%) (14% vs. 2%, p<0.05) (Figure). Conclusions This study demonstrated that 44% of HFmrEF patients improved LVEF following treatment but 19% patients reduced LVEF. Reduced LVEF was associated with poor prognosis.

Resynchronisation Therapy

Cardiac resynchronisation therapy (CRT) is an efficacious and cost-effective therapy in patients with highly symptomatic systolic heart failure and delayed ventricular conduction. Current guidelines recommend CRT as a class I indication for patients with sinus rhythm, New York Heart Association (NYHA) functional class III or ambulatory class IV, a QRS duration ≥120ms, and left ventricular ejection fraction (LVEF) ≤35%, despite optimal pharmacological therapy. Recent trials resulted in an extension of current recommendations to patients with mild heart failure, patients with atrial fibrillation, and patients with an indication for permanent right ventricular pacing with the aim of morbidity reduction. The effectiveness of CRT in patients with narrow QRS, patients with end-stage heart failure and cardiogenic shock, and patients with an LVEF >35% still needs to be proved. This article reviews current evidence and clinical applications of CRT in heart failure and provides an outlook on future developments.

Abstract Background Percutaneous pulmonary valve implantation (PPVI) is being increasingly used as a minimally invasive corrective procedure for right ventricular outflow tract (RVOT) dysfunction. Ten-year survival following PPVI is estimated at over 90% due to the durability of the various bioprosthetic valves. However, infective endocarditis (IE) remains a potential complication of such valves with significant morbidity and mortality. We evaluated the presenting symptoms, clinical features, pathogens, and outcomes of patients with IE following PPVI to identify opportunities to improve early diagnosis and management. Methods A convenience sample of patients at a large Pediatric Cardiology practice in Northern Virginia was queried for PPVI and IE from January 1, 2016, to June 30, 2019. Manual chart review was done to extract clinical points of interest and descriptive analyses were performed. Patients were classified as having IE per modified Duke’s criteria. Results We identified 14 patients who underwent PPVI. Five of these patients (36%) developed IE. All IE patients had underlying Tetralogy of Fallot and none had previous episodes of IE. 60% of patients with IE were male with a median age of 26 years old (IQR 20–30). Four IE patients had a Melody valve and 1 had a SAPIEN valve. The median elapsed time between PPVI and IE diagnosis was 128 days (IQR 32–391) with a median duration of illness prior to the diagnosis of IE of 6 days (IQR 5–9). All IE patients had to present fever. 40% of IE patients had to present chest pain and 20% had presenting musculoskeletal pain. All IE patients had an elevated initial C-reactive protein (CRP) with a median value of 13.1 mg/dL (IQR 12.5–15.2). The median initial white blood cell count was 9.3 × 103/μL (IQR 8.1–10.3). The median duration of bacteremia was 1 day (IQR 1–2). A pathogen was recovered in all five IE patients with different organisms amongst the patients: coagulase-negative Staphylococcus species were recovered in patients who developed IE within 60 days from PPVI (Staphylococcus lugdunensis and Staphylococcus epidermidis) whereas coagulase-negative Staphylococcus species and oral commensal organisms were found in IE patients beyond 60 days from PPVI (Staphylococcus sanguinis, Gamella haemolysans, and Neisseria elongata). The initial echocardiogram did not show vegetations in any of the patients and 40% went on to have sternotomy with valve replacement. There were no deaths. Conclusions With an increase in PPVI, clinicians should have a high index of suspicion for IE in patients with underlying Tetralogy of Fallot who present with fever and elevated CRP, regardless of elapsed time from PPVI or valve type. Empiric antimicrobial therapy for suspected IE following PPVI should remain broad with other possible pathogens beyond coagulase-negative Staphylococcus species.

Abstract Background Left ventricular negative remodelling after ST-segment elevation myocardial infarction (STEMI) is considered as the major cause for the poor prognosis. But the predisposing factors and potential mechanisms of left ventricular negative remodelling after STEMI remain not fully understood. The present research mainly assessed the association between the stress hyperglycaemia ratio (SHR) and left ventricular negative remodelling. Methods We recruited 127 first-time, anterior, and acute STEMI patients in the present study. All enrolled patients were divided into 2 subgroups equally according to the median value of SHR level (1.191). Echocardiography was conducted within 24 h after admission and 6 months post-STEMI to measure left ventricular ejection fraction (LVEF), left ventricular end-diastolic diameter (LVEDD), and left ventricular end-systolic diameter (LVESD). Changes in echocardiography parameters (δLVEF, δLVEDD, δLVESD) were calculated as LVEF, LVEDD, and LVESD at 6 months after infarction minus baseline LVEF, LVEDD and LVESD, respectively. Results In the present study, the mean SHR was 1.22 ± 0.25 and there was significant difference in SHR between the 2 subgroups (1.05 (0.95, 1.11) vs 1.39 (1.28, 1.50), p < 0.0001). The global LVEF at 6 months post-STEMI was significantly higher in the low SHR group than the high SHR group (59.37 ± 7.33 vs 54.03 ± 9.64, p  = 0.001). Additionally, the global LVEDD (49.84 ± 5.10 vs 51.81 ± 5.60, p  = 0.040) and LVESD (33.27 ± 5.03 vs 35.38 ± 6.05, p  = 0.035) at 6 months after STEMI were lower in the low SHR group. Most importantly, after adjusting through multivariable linear regression analysis, SHR remained associated with δLVEF (beta = −9.825, 95% CI −15.168 to −4.481, p  < 0.0001), δLVEDD (beta = 4.879, 95% CI 1.725 to 8.069, p  = 0.003), and δLVESD (beta = 5.079, 95% CI 1.421 to 8.738, p  = 0.007). Conclusions In the present research, we demonstrated for the first time that SHR is significantly correlated with left ventricular negative remodelling after STEMI.

Abstract PurposeTrastuzumab improves survival in patients with HER2+ early breast cancer. However, cardiotoxicity remains a concern, particularly in the curative setting, and there are limited data on its incidence outside of clinical trials. We retrospectively evaluated the cardiotoxicity rates (left ventricular ejection fraction [LVEF] decline, congestive heart failure [CHF], cardiac death or trastuzumab discontinuation) and assessed the performance of a proposed model to predict cardiotoxicity in routine clinical practice.MethodsPatients receiving curative trastuzumab between 2011-2018 were identified. Demographics, treatments, assessments and toxicities were recorded. Fisher’s exact test, chi-squared and logistic regression were used.Results931 patients were included in the analysis. Median age was 54 years (range 24-83) and Charlson comorbidity index 0 (0-6), with 195 patients (20.9%) aged 65 or older. 228 (24.5%) were smokers. Anthracyclines were given in 608 (65.3%). Median number of trastuzumab doses was 18 (1-18). The HFA-ICOS cardiovascular risk was low in 401 patients (43.1%), medium in 454 (48.8%), high in 70 (7.5%) and very high in 6 (0.6%).Overall, 155 (16.6%) patients experienced cardiotoxicity: LVEF decline≥10% in 141 (15.1%), falling below 50% in 55 (5.9%), CHF NYHA class II in 42 (4.5%) and class III-IV in 5 (0.5%) and discontinuation due to cardiac reasons in 35 (3.8%). No deaths were observed.Cardiotoxicity rates increased with HFA-ICOS score (14.0% low, 16.7% medium, 30.3% high/very high; p=0.002). ConclusionsCardiotoxicity was relatively common (16.6%), but symptomatic heart failure on trastuzumab was rare in our cohort. The HFA-ICOS score identifies patients at high risk of cardiotoxicity
